Green HVAC Resource
As our supply of fossil fuels decrease and the price increases people are much more concerned about how green energy in their homes can save resources and money. Heating, cooling and lighting consume 67% of all the electricity that’s generated.
Green HVAC Transition Guide
1. Incorporate HVAC systems early in the design phase
Benefit |
Makes installation easier and more efficient. Dedicated chases will cut down on labor costs and project complexity. |
Process |
One or two meetings with the architect or engineer early in the building process. |
Details/ Materials |
Systems can often be smaller in green homes with increased insulation saving money |
2. Size HVAC system to meet actual loads using Manual J
Benefit |
System is sized appropriately for actual home needs. Reduced heating bills and protects air quality. |
Process |
Careful calculations based on room and home size. The home’s orientation, insulation and window placement affect the heating and cooling load. |
Details/ Materials |
Manual J is software from ASHRAE |
3. Specify high efficiency furnaces and air conditioning units
Benefit |
Save clients energy and money. Increases comfort and reduces pollution. Reduced peak grid load. |
Process |
Research which manufactures sell the highest efficiency units in your area. |
Details/ Materials |
Energy Star models furnaces or air-conditioners with a SEER of 14 or higher. |
4. Seal around electrical outlets and all wall penetrations
Benefit |
Small penetrations can mean a lot of heat loss over the life of a building. |
Process |
Squirt a small amount of foam to seal each penetration |
Details/ Materials |
One can of expansion foam. Look for products that use HFC rather than HCFC or CFC as propellants. |
5.Size ducts appropriately using Manual D heat loss calculations
Benefit |
Ducts are sized appropriately for actual room by room needs. Heat or cooling is efficiently blown to all rooms of the house effectively. |
Process |
Ducts are installed and sized for maximum performance |
Details/ Materials |
Manual D is software from ASHRAE |
6. Seal all ductwork with mastic
Benefit |
Leaky ductwork looses pressure and wastes as much as 20% of conditioned air as it travels. |
Process |
Brush mastic over any joints or bends |
Details/ Materials |
Low VOC mastic is a paste available in home stores. Do not use duct tape as it dries out all falls off. |
7. Insulate all ducts in the attic or crawl space
Benefit |
When warm air ducts pass through unheated areas, they looses efficiency. Insulation will help lessen the energy loss. |
Process |
Carefully wrap ductwork with duct insulation and seal. |
Details/ Materials |
Specific duct insulation is available-use as high R-value as possible |
8. Design adequate returns to keep the house pressure balanced
Benefit |
Negative pressure can draw carbon monoxide from gas water heaters and furnaces due to inadequate returns. |
Process |
Use Manual D and S software from ASHRAE |
Details/ Materials |
Make sure that each room has adequate return ducts or doors are undercut sufficiently to allow air flow |
9. Install a whole house fan
Benefit |
A fan will help circulate air and reduce the need for air-conditioning by sucking the hot air out of the house quickly. It can also be used for nighttime cooling |
Process |
A insulated, airtight seal is necessary to prevent air leakage. A whole house fan is usually installed in the attic. |
Details/ Materials |
Find and energy star rated product. Install a fan that has more than one power setting. |
10. Install a heat recovery ventilation system
Benefit |
Recovers heat from exhausted indoor air and transfers it to the incoming fresh air stream |
Process |
Necessary if the house has less than 0.35 natural air changes per hour. |
Details/ Materials |
System installed in conjunction with the furnace or A/C unit. |
“How will “Going Green” make me more money?”
Green is not simply getting more respect; it is rapidly becoming a necessity as corporations—as well as home builders, retailers, health care institutions, governments, and others—push green buildings fully into the mainstream over the next five to ten years. The price of natural gas and home heating fuel has doubled, or even tripled in some areas. Consumers are looking for leadership and guidance from experts in the field on how they can retrofit their homes to save energy.
“I thought green was just for tree huggers”
Green Homes no longer look like they did in the 70’s. They now look normal and very diverse. Professionals who would not consider themselves “greenies” are adopting green practices. People can now see the real benefit of these practices and want to implement them in their own lives.
“How will I talk to my customers about my green practices?”
If a homeowner considers a project too costly, remind them that the cost of fuels will continue to steadily rise and the payback period may be shorter than they think.
Increase home value. A home with a lower energy will stand out in the real estate market.
Quieter HVAC will create a more comfortable living environment.
In a tightly built home, a heat recovery ventilation system will provide clean air without wasting valuable heat.
Teach customers about the important of removing hot humid air from bathrooms.
Remember to take the solar orientation of the house into account some existing systems can be unnecessarily over-sized.
“Why should I care about the environment?”
- Domestic natural gas supplies are dwindling and importing natural gas is fraught with difficulty.
- So much of the electricity used is produced in plants that burn fossil fuels. If we can lower consumption reduces greenhouse gas emissions.
- The grid is already stretched to capacity and increasing electricity production means either new coal-fired plants (contributing to climate change) or nuclear (will take a long time to come online) or renewable energy (will take a long time to transition)
“What kind of training am I going to give my team?”
- Greenbuilding.com has a team of green building specialists. One of our trainers can come to your business to train your team.
- We have HVAC specialists
- We can provide a one-day training to get your team ready to transition to green. This training will include marketing your business as green.
“What should I do first?”
- Read our Green HVAC Transition Guide below.
- Our guide is organized with the easiest changes listed first and those that may take longer listed last.
Join host Chris Stanton and his guest, David Johnston, as they explore such territories as sustainability, green building, future-proofing your home, and radically transforming the entire construction industry. 
Excerpt from the Residential Green Certification Training in Golden. David speaks on the topic of Indoor Air Quality.

free sheet music for piano
Piano sheet music, however, is not totally out of the music scene. Song writers nowadays still publish piano sheet music on sheets of paper. With the availability of advanced computer technology, many kinds of piano sheet music are now offered in computer-readable formats. They can be easily purchased and downloaded over the Internet.
Common pieces are sold from $3 to $5, while a piano sheet music collection of most recent hits sells at around $10 to $25. Rare and old piano sheet music, usually of classical songs, are priced at about $50.
Free piano sheet music can also be downloaded from the Internet. They are mostly old musical pieces with an expired copyright, such as the compositions of famous musicians Mozart, Brahms and Beethoven.

If you don't find the sheet music of your choice online, especially if it is rare, you may look for it in music stores near you. Some websites also offer listings of music stores where you can find both the most popular and hard-to-find sheet music, old and new alike.
Sheet Music provides detailed information on Sheet Music, Free Sheet Music, Piano Sheet Music, Guitar Sheet Music and more. Sheet Music is affiliated with Music Education Theory
I guess I agree to pay a bit
I guess I agree to pay a bit more for newer music sheets but the classical ones should be able to be downloaded for free. Every musician first starts with the classics and the fact that they are free is a big help. But sadly, a lot of the free content out there is not accurate and sometimes you have to pay to get the best sheets.

The size of the home and the
The size of the home and the amount of insulation in the home may affect the choice of a heat pump, as it will affect the choice of something like a wood burning stove or window air conditioner.
Heating efficiency for air source heat pumps is indicated by the heating season performance factor (HSPF), which is the total space heating required during the heating season, expressed in Btu, divided by the total electrical energy consumed by the heat pump system during the same season, expressed in watt-hours.
